- Logistic[ <Mean>, <Scale>, x ]
- Logistic[ <Mean>, <Scale>, x, <Boolean Cumulative> ]
- Logistic[ <Mean>, <Scale>, <Variable Value> ]
- Logistic[ <Mean μ>, <Scale s>, x ]
- Creates probability density function (pdf) of logistic distribution with parameters μ, s.
- Logistic[ <Mean μ>, <Scale s>, x, <Boolean Cumulative> ]
- If Cumulative is true, creates cumulative distribution function of logistic distribution, otherwise creates pdf of logistic distribution.
- Logistic[ <Mean μ>, <Scale s>, <Variable Value v> ]
- Calculates the value of cumulative distribution function of logistic distribution at v, i.e. the probability P(X≤v) where X is a random variable with logistic distribution given by parameters μ, s.
- 備註: Returns the probability for a given x-coordinate's value (or area under the logistic distribution curve to the left of the given x-coordinate).
CAS Syntaxes
In CAS View only following syntax is supported:
- Logistic[ <Mean μ>, <Scale s>, <Variable Value v>]
- Calculates the value of cumulative distribution function of logistic distribution at v, i.e. the probability P(X≤v) where X is a random variable with log-normal distribution given by parameters μ, s.
